Fit Note: Please do not assume your size, please use our size chart. If in doubt, email questions to contact@desotosport.com. Triathlon apparel is meant to fit next-to-skin. This is to eliminate potential chafing, and unnecessary drag during the swim, bike and run. If you’re not comfortable with this type of fit and or are between sizes, we recommend sizing up. Garment will fit the most snug the first time you put it on, it will relax slightly once wet.

What makes ours different?  Our Skin Cooler fiber is designed to feel and perform like silk (from a silkworm).  Through Biomimicry, we took the virtues of this natural fiber and created a synthetic silk.  It will keep you cool in hot weather and cooler when it is wet.  Put it on and you will instantly feel the cool sensation.  Wet it and you will notice a drop in the surface temperature of the skin between 7 and 10 degrees.

A MEDICAL TESTIM0NIAL:  We received this letter from Dermatologist and Mohs Surgeon Dr. Michael Bax.* 

 I am an avid runner and triathlete and I recently discovered your Skin Cooler products, of which I'm a huge fan.  I have been wearing them for a few months now and couldn't be happier.  I am a dermatologist and Mohs surgeon at Roswell Park Cancer Institute in Buffalo, NY.  Every patient I see is plagued by basal cell carcinoma, squamous cell carcinoma, or melanoma.  I recommend your products to my active patients on a daily basis.  It allows them to continue their active lifestyle while protecting themselves from the sun. I find your product to be far superior to all other cooling and sun protective lines.  I truly appreciate your efforts and innovations.

Note: No garment should ever be a substitute so we always recommend you wear sunscreen underneath these, and all, products. It is crucial to keep in mind that a sunscreen's (whichever brand you may choose) SPF/UPF rating refers only to its ability to protect skin from UVB radiation. Because we know that UVA damage can be just as insidious, it is essential for the health of your skin that you use a sunscreen that contains the UVA-protecting ingredients of titanium dioxide or zinc oxide.
